What is Cancer pathway

Cell growth is activated, when the cell receives a signal from growth factor molecules. These molecules bind with the receptor proteins on the outside of the cell membrane.The signal molecules trigger the receptor proteins to become phosphorylated,which intiatiates a chain of reactions, that in turn activates the RAS protein the signal transduction pathway continues the multistep sequential process like a roll of falling dominoes.Each protein interaction triggers a new set of proteins ,which inturn triggers even great number of proteins.The final proteins activated in this chain reaction are transcription factors which enters into the cell nucleus generating a response.The transcription of an mRNA is translated into a protein that triggers cell growth.
